WINDOW.

SPECIFICATION forming part of Letters Patent No. 279,364, dated June 12,1883.

Application filed October 16. 1852. (No model.)

To all whom it may concern:

Be it known that I, MILTON L. EDMUNns, of Danbury, in the county of'Woodbury and State of Iowa, have invented a new and useful Improvementin Windows, of which the following is a full, clear, and exactdescription.

The invention consists in an improvement of the means employed for theescape of flies and other insects, as well as for ventilation, withouthoisting windows, as hereinafter described.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a front elevation of part of a window constructed accordingto my invention. Fig. 2 is a section of the same, taken on the line 93'a." of Fig. 1. Figs. 3 and 4 are details of the apparatus in section.

Over any one or all of the panes, a, of a windowI propose to arrangeavalve, Z1, preferably of circular form, but which may be of other form,to open a passage, 0, over the pane, as represented in the upper part ofFig. 2, or close it, as shown in the lower part of said figure, theobjects being to provide for the escape of the .fiies and forventilation, as above described.

. In carrying out my invention I prefer to employ roller-valves I),having a groove, (1, along one side, and mounted on pivots 6, so that,being turned by a screw, f, and teeth 9, the screw having a thumb-bit,h, projecting out of the inclosing-case for the roller, it may bereadily shifted for opening or closing the passages. The said caseconsists of the front plate,

' i, and back plate, j, connected together by bars k, and attached tothe under side of the rail or bar l of the window-sash, with plates atconnected to them at the ends for the pivots of the rollers, andcontaining a notch, a, in the lower end to receive the upper edge of thepanes for supporting them thereat. The connecting-bars k for the twoplates of the case are attached to them below their upper edges, inorder that they may overlap the lower edges of the sashrails Z, and befastened thereto by screws 0, the rails being rabbeted to let the platesin flush with the sides of the rails. The inside plate, 17, is curvedinward at the lower edge toward the glass for a finish. The rollers willfit snugly between the side plates ofthese inclosing-cases, and theshape of the groove may be such as to for effectually closing againstthe weather.

I am aware that it is not new to provide a valved or dampered outlet atthe top of a win dow-screen; but

WVhat I do claim as new and of my inven tion is 1. As an improvement invalves or dampers over window panes or screens, a roller-valve, I),having the groove d, and arranged on pivfor the purpose specified.

2. The front and back plates, ij, connected by bars k, in combinationwith the rabbeted sash-bar Z, overlapped by bars 11 the screws 0, andthe bearing-plates m, notched at -n,'wher'eby avalve may be supportedbetween the sash frame and one or more panes, as described.

3. The combination of the grooved rollervalves 1), inclosingplates z andj, and means for operating said roller-valves, with a window,substantially as described.

4. The combination of inelosing-plates 12 j, roller-valves b, and endplates, m, with the panes a and rails Z of a window, substantially asdescribed.

5. The inclosing-platcs 1 1', connected together by bars k and endplates, m, and connected to the rails Z of the window, substantially asdescribed.

6. The pivot-supporting end plates, m, having notch n, in combinationwith roller-valves band the window-panes a, substantially as described.
